General Description
Economizer for controlling the pneumatic cleaning function of industrial dust
collection systems.
The pressure differential is digitally controlled by an internal transducer allowing
to determine filter obstruction with accuracy.
The device has three output relays contacts and two digital input contacts.
A large, bright display is provided for reading the filter obstruction level, the
active solenoid valves and any alarms in any moment.
Technical Specifications
Casing
Made of insulating, ABS base and polycarbonate lid.
Degree of protection to water and dust: IP65 (EN60529).
Shock resistance: IK08/07 (8 joule) (EN62262).
Performance Of The Device
Dedicated software program, managed by the microprocessor, easy to set up
and consult, facilitates the use of the instrument also by users unfamiliar.
Power voltage 24 Vdc.
Output voltage 24Vdc.
LED display with 7 segments, 3 digits 0.8” each.
Three alarm relay.
Micro SD memory card for data storage, extractable for consultation.
Sampling is performed every 10 seconds, the time interval is editable.
Four operation modes: manual; automatic;
automatic with forced cycle; proportional.
Operating times expressed in seconds with selectable ranges for any
application (option pause time in minutes).
Pressure measurements expressed in kPa optional in inch Wc.
Washing function with the fan off (post-cleaning) through the “dP fan”
threshold in the automatic/automatic with forced cycle/proportional modes
and through contact in the manual mode with up to 99 cycles that can be
selected.
Total and partial hour counter for maintenance.
Three alarm relays.
Maximum dP (filter obstructed) alarm.
Minimum dP alarm (broken sleeve/cartridge), with possibility of
inclusion/exclusion.
Solenoid valve not working alarm.
Filtering element maintenance deadline alarm (with on/off selection).
External contact cleaning activation.
Compressed air presence enable input.
Pre-coating function (with possibility of inclusion/exclusion).
4-20mA output proportional to dP reading for remote pressure reading.
Manual solenoid valve activation.
Setting the current date and time associated with the archiving historical
data on the SD card, where are stored the detected values.
